Windows: Several Kindle Fire hacks have surfaced since its release, but now you can get them all in one handy utility. The aptly named Kindle Fire Utility will root and update your device as well as repair permissions, install the TWRP recovery app, and more.

Technically the app itself isn't doing the rootin' and the hackin', but it puts all the stuff you'll need in one place. If you're mildly comfortable with the command line and want to mess around with your Kindle Fire, this is a handy little utility that'll make many common operations a bit easier.
